My invention relates to new and useful Figure 3 is a sectional Viewtaken on line improvements indust guards for the jour- 3-3 of Figure lon an enlarged scale; nal boxes of raiivay cars and has for an` Figure 4is a sectional View taken on line object to, provide a dust guard thatwilli fit 4&4 of Figure l; 5 closely around the dust guard bearing otFigure 5 is a sectional view taken on line the axle to exclude the dustand prevent of Figure l; the escape of oil and waste. Figure 6 is asectional Viewl taken on line One of the objects ofthe present invention6-6 ofFigure l. y is to provide a dust guard that will be ex- Referringnow to the several views and 10 tremely light in weight and otlieieut inFigure l in particular, it will be seen that Servceh my iinproved dustguard consists of a sheet Still another object; of the inventien is tolnctat plate l having the outstanding flanges provide a dust guardcomp-rising a metal 2 the sides. The bottom of the plato holder orframe,in which there is placed! is. rounded, as at 3, while the top 4 is flatl5 a ring, which in turn is formed with a pliacross its entire width.rlhe top. of the 3g able material, such as lainp wicking or cetplate isprovided with the oifset flange 5, ton webbing securely heldin a metalbackwhile its edge 6 is slightly curled, as may ing. besee-n in Figures1 and 2.

Still another object; ofthe invention is to It will also be seen thatthere is the smallr 2o provide a dust guard formed off relatively flange7' at the bottom with the slightly thin sheet metal, in which there is awiclr curled edge Si, thus the edge 8 and the top crimped i-n a` metalbacking, which wick 6 ofthe flange 5l being in the same vertical withits metal backing may easily be replane, sothatz when the dust guardv isplaced moved from the plateand a new` one inin the dust box (not shown),it will bear 25 sorted when necessary., against the opposite walls ofthe same from 1p. Sti-ll anotherI object ofthe invention is to the mainpla/teI I. provide a dust guard comprising a plate, The central portionof the plate l is cut in which there tits the renewable wick, the out,as at 9, the-opening being slightly larger said ring being broken at itsupper porthan the circumference of the car axle (not '3o tion andfitting within a small removable shown). bearing block, which 1n turnmay rest on About the wall ot the circular opening` the axle in theJournal box. 9, there will be seen; the pressed ribl 10,

till another object of the invention is to which extends from the pointll near the provide a dust guard that is extremely cheap top of theplate around to the point 12, or ai: to manufacture and wherein the ringwick in other words, the rib, nearly circ-umscr-ibmay be easily renewedand the metal plate ingthe opening. itself` be used indefinitely. Thereis a slight circular space 13 belVith these and other objects in view,tween the rib l() and the edge of the periphthe invention consists incertain new and eral wall of the opening 9, which, ispa-rtiv 41'?. novelarrangements and combination oi cutout to form lips in staggeredrelation, parts as will be hereinafter more fully deas maybe seen inFigure l and the several scribed and pointed out in the claims.sectional views.

Referring now to the drawings showing Referring for the moment to Figure5 a preferred embodiment, which is av section on line 5-5 of Figure l,

Figure 1 is a plan view of my improved it will be seen that theperipheral edge 14 dust guard showing the wick ring in posiat thispoint. is in the normal plane of the tion; plate. However, the meta-l'is then slit or cut,

Figure 2 is a sectional view taken on line as at l5 and I6, to form thelug or lip 17,

2 2 and looking in the direction of the as may be seen in Figure 6, and.this metal 5^@ arrows, but with the Wick removed; ispressedv inwardly,as viewed from Figure lit-e 2 or, in other words, is offset from thepart 14 to form a retaining lip.

There are a number of these lips formed in the same Way, such as 18, 19,20 and 21, the metal left inthe Original plane also forming retaininglips, alternately thereof.

Now at the top of the circular opening, the metal is cutand offset toform two lips 22 and 23, while the central section 24: between" thesetwo lugs is offset slightly in the oppof site direction, as may be seenat 25, (see Figure 4) the purpose of these three lugs being to receiveand hold a small bearing block` Y shown) having a large central opening,togetherV Now this crimp metal ring 28 has its ends fitting Within theopposite notched ends of the bearing block 26, While the metal ring fitsunder the lips 17, 18, etc., and also bears against the remainingstaggered lips that are formed between the lips 17, 18, etc., and isthus tightly held in place. The small bearing block holds these ends ofthe split ring together and will rest and bear on the aXle (not shown).Y

Any time thatit is desired to put in a new bearing block, ring or Wick,it is a simple matter, when the axle of course is out of the journal boxto slip the old ring or bearing block from out of the lips and put 'anew one in its place. Y Y

From the foregoing, it will be seen that l have produced a metal dustguard that isY extremely cheap to manufacture, as the plate itself maybe quickly stamped out by the proper dies, while the small metal ringwith the wick maybe madeon a'crimping machine that has been fitted upfor theV purpose and of course the small bearingblocks may be made at aminor expense.' Y

Thus, the entire dust guard maybe made at a very economical price andthe crimped ring with the wick. may be renewed at a cheap price and thedust guard'plate used indelinitely. l

Many slight changes might be made without in any way departing from thespiritY and scope of the invention.

Having thus described my invention, what y I claim 1s new and desire tosecure by'Letters Patent is Y 1. A dust guard formed of a metal sheetwith a iXedly held split metal ring having an axle engaging memberassociated ytherewith, integral means about the opening for holding thering in position, and plug means having its ends notched and locatedvertically centrally of the opening and adapted to rest on the aXle andreceive the ends of the split ring. Y

2. A dust guard formed of a metal sheet having a large central opening,a wick having a metal backing crimped thereto and the wick and backingformed into a split ring the ends of which are substantially spaced`from each other, the walls about the Yopening of the dust guard cut toform lips for engaging the metal backing of the split ring and forholding the said ring tightly lin position andv against rotation, mea-nsformed at the top of the opening for removably holding an axle bearingplug a plug having notched ends carried by said means and the ends ofthe metal backing oi' the ring ammed within the notched ends of the plugto thereby complete the splitring.

3. A dust guard formed of a metal sheet having a large central opening,a pressed groove around the peripheral wall of the opening andterminating short of a median line, the walls about the opening beingsplit and bent to-form staggered lips and a pocket formed at the top ofthe opening and positioned between the ends of the said reinforcinggroove a plug having notched ends fitting in said pocket and adapted tobear against an axle and a wick in the form of a split ring and havingits outer edge crimped within a metal backing, the Wick and the metalbacking held within the lips about the opening of the plate and themetal ends of the split ring fitting Within the notched ends of theplug.
